Clear Theme/CSS Cache in Magento 2 (7 answers)

Closed 2 years ago.

I am pretty new to Magento2 and my question may sound banana to most of you. I would like to know how can I compile my less file.

app/design/frontend/my_theme/web/css/source/_layout.less

thank you so much in advance

Answer 1

Remove var and pub/static folder and deploy static content again as per below commands.

rm -rf var/ pub/static/
php bin/magento setup:static-content:deploy
chmod -R 777 var/ pub/static/

Answer 2

Just run php bin/magento setup:static-content:deploy from your project root folder.

You might have to remove contents of pub/static or to be more granular affected files by your changes.
